naum gabo - Constructivism

 ''he began to experiment in multi-media including plywood and cardboard. He also worked with galvanised iron, a material more associated with industrial construction rather than the fine arts. Head No. 2 (1916, Tate London), a Cor-ten steel sculpture of a head, is a fine example from this period, as is his Constructed Torso (1917, Tate), made from cardboard''

''The Manifesto focused on separating art from the conventions of line, colour, volume and mass. They also stated that art should accompany man everywhere, 'at the workbench, at the office, at work, at rest, and at leisure; work days and holidays, at home and on the road, so that the flame of life does not go out in man.' The ideas of the Manifesto were expressed in Gabo's Kinetic Construction (Standing Wave) of 1920, a vibrating wire powered by an electric motor. A replica can be seen in the Tate Gallery, London.''
